WP_Admin_Bar::add_group( array $args )

Add a group to a menu node.

Parameters

$args

(array) (Required) Array of arguments for adding a group.

  • 'id'
    (string) ID of the item.
  • 'parent'
    (string) Optional. ID of the parent node. Default 'root'.
  • 'meta'
    (array) Meta data for the group including the following keys: 'class', 'onclick', 'target', and 'title'.

More Information

  • Toolbar items are also called “nodes”. Nodes can be parents for other nodes, which creates dropdown menus. When adding a group you’re actually adding a group node. Group nodes are not visible in the Toolbar, but nodes added to it are.
  • This function is a method of the WP_Admin_Bar class and $wp_admin_bar global object, which may not exist except during the ‘admin_bar_menu‘ or ‘wp_before_admin_bar_render‘ hooks.
  • The Toolbar replaces the Admin Bar since WordPress Version 3.3.
